Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

You can probably find an online link about how extreme temperature changes are not the ideal way to heat a home and cost more in the long run.I don't know what the local rental rules are where you are, but look them up and see if you can give her notice. 

@MikeLambert thanks for all the insight on Tulum I love the town and would like to purchase A condo For myself don’t care if it doesn’t make much money  but obviously would like a great location I am a dual citizen and want own property in MexicoI probably won’t stay there much if at all I just love to buy real estate one of my addictions 😂Searched online There are so many developments from $100k - $200k would be my comfort level if any of you guys have recommendations on location would appreciate it 

Hey @Vhernadette Sasing, with your high income and limited time, a solid approach might be investing in cash-flowing assets that are low maintenance, like passive multifamily syndications, or exploring online businesses with recurring revenue models (e.g., SaaS, subscription-based e-commerce). 

It's challenging to distinguish between genuine advice and potential scams in the vast sea of information available online.

Permit expeditors (they usually know how hard it is to do in that area too) are great if everything is not already completely online with the jurisdiction.

so the thing you're looking for is likely something you can't find online.  

just algebra, or you can plug it in online calculator.If your resulting DSCR is 1.1, not good.

Check online reviews and interview multiple contractors to compare bids.

It does this using a technology called the block chain which is pretty revolutionary.
